Abstract:
(EN) In an angularly adjustable, releasably lockable ball joint, the ball (1) has a surface (3) covered with regular polygonal patterns (a, b) of spaced-apart protuberances (4). The protuberances (4) define concavities (7). An actuator tip (6) is provided to penetrate at least one concavity (7) and simultaneously contact all of the protuberances (4) of the pattern (a, b) to lock the ball (1) and actuator (5) together, thereby fixing the orientation of shanks (2) attached to the ball (1) and actuator (5).
(FR) Dans ce joint à rotule, à blocage amovible et réglage angulaire, la rotule (1) présente une surface (3) couverte de motifs (a, b) polygonaux réguliers de protubérances (4) espacées les unes des autres, lesquelles délimitent des concavités. Un embout (6) d'actionneur est monté de manière à pénétrer au moins dans une concavité (7) et entrer simultanément en contact avec toutes les protubérances (4) du motif (a, b), afin de bloquer ensemble la rotule (1) et l'actionneur (5), fixant ainsi l'orientation des tiges (2) attachées à la rotule (1) et à l'actionneur (5).
